A group of more than 400 North Korean supporters and performers have travelled to Pyeongchang, South Korea for the Games.

Their visit was controversial with some South Koreans who questioned the North's commitment to reconciliation.

North Korea's attendance at the Winter Olympics came as a surprise development after a year of increasing tensions between Pyongyang and the international community over its nuclear ambitions and repeated missile tests.

The South Korean government invited the North to join the Games saying it was a chance at dialogue and rolling back tensions. But some South Koreans have staged protests warning it would merely give the North a platform for propaganda.

The decision to integrate North Koreans into the South's women's ice hockey team was particularly controversial as it meant that some of the South's athletes would get less of a chance to play.
